This is a simple but important lesson. When you work with people that are always angling for more, you’ll learn that they are never satisfied. I respect employees and investors that negotiate to get what they deserve. You always should. But there are some people that aspire not for their fair share but for an endless share. Beware of people that will feed themselves extra at the expense of others getting what they deserve. These people are toxic, and they don’t value the collective health of the team. Most leaders are pleasers (and I admit, I love keeping people happy), but you can’t feed greed. Doing so always backfires.
